Pharmacological manipulation of bone maturation should be used to preserve final height in short children (FOR)

Mericq Veronica

Short children who are not GH deficient, often necessitate a different strategy, especially those with acceleration of bone age, which greatly limits height poten¬tial and the time available for growth. In this setting the use of agents to delay bone maturation has been explored to improve adult height. Estrogen principally modulates epiphyseal fusion in females and males through ERα. Aromatase inhibitors (AIs) block androgen to estrogen conversion, slowing down grow...

Use of aromatase inhibitors in short children and adolescents to optimize final height: A current practice survey

Zepeda Diego , Mericq Veronica

Introduction: Management of pediatric patients with short stature and poor adult height prognosis it’s challenging and effectiveness of treatment with growth-promoting agents is controversial when linear growth is ending. Aromatase inhibitors (AI) have become a therapeutic option as they promote slowdown of bone maturation and increase final height, but yet is a non-approved indication.Aim: To conduct a survey abou...

Premature Adrenarche is Associated to Precocious Thelarche but not to Precocious Gonadarche or Pubarche in Chilean Adolescents

Pereira Ana , Corvalan Camila , Mericq Veronica

Background: Premature adrenarche (PA) has been associated to increased metabolic risk. Areas of controversy regarding associated co-morbidities are precocious pubarche, PCOS and lower birth weight, which may depend on ethnic background.Objective and hypotheses: To describe the risk of precocious thelarche (PT, <8 years), pubarche (PP, <8 years F, <9 years M) and gonadarche (PG, <9 years) in children with premature adrenarche.<p class=...

Identifying several patient-related factors that predicted permanent growth hormone deficiency (GHD)

Mericq Veronica , Kariyawasam Dulanjalee , Iñiguez German , Polak Michel

GHD is the most common endocrine disorder in children with short stature (~1 in 4000). Appropriate diagnosis should synthesize auxological, biochemical and neuroradiological data. However, until now there are significant controversies, especially from the laboratory interpretation. A false positive diagnosis can lead to a significant wasted expenditure and unnecessary exposure to rare potential adverse effects. Given these open issues about biochemical diagnosis of GHD in chil...

High DHEAS (HD) in Girls Determines Earlier Pubertal Maturation and Mild Hyperandrogenism throughout Pubertal Development

Pereira Ana , Merino Paulina , Iniguez German , Corvalan Camila , Mericq Veronica

Background: Premature adrenarche (PA),characterized by high concentrations of DHEAS,has been considered a benign condition until recently,where associations to increased metabolic risk and PCOS have arisen,which may depend on ethnic background and infancy weight gain.Objective and hypotheses: To determine whether PA in girls determines:i)a different timing of pubertal events, and ii)a different pattern of Ovarian morphology/hormones and adrenal hormones....

Prolacrin associates to adrenal androgens during adrenarche

Iñiguez German , Pereira Ana , Ferrer Pedro , Mericq Veronica

Premature adrenarche (PremA), is associated to increased adiposity and in girls to earlier puberty and adverse metabolic profiles. Recently, the use LC-MS/MS studies demonstrated adrenal production of more potent androgens:11-oxygenatedC19 steroids. Defining the mechanisms that regulate adrenal C19 steroid production has been elusive. We recently showed that genetic determinants of DHEAS during adrenarche differed from those identified during adulthood. One top variant was at ...

Pubertal Events, Reproductive and Growth Hormones and Predictive Factors in Healthy Girls with Transient Thelarche.

Soto Julio , Pereira Ana , Busch Alexander , Almstrup Kristian , Corvalan Camila , Juul Anders , Mericq Veronica

Context: Transient thelarche (TT) corresponds to the appearance, regression and subsequent reappearance of the breast bud in girls. Only a single study about its frequency and progression is available (Lindhardt Johansen JCEM 2017).Objective and Hypotheses: To determine whether girls with TT girls (group 1) compared to girls without TT (group 2) show differences in i) timing/sequence of pubertal events ii) pattern of rep...

Premature Adrenarche in Girls at Pubertal Onset is Associated with High Androgens, but Lower AMH Concentrations

Merino Paulina M , Pereira Ana , Iniguez German , Corvalan Camila , Mericq Veronica

Background: Premature adrenarche (PA) has been considered a benign condition. Recently, associations with increase androgen levels and PCOS have arisen.Objective: To determine whether PA in children at pubertal onset (TII) determines a different timing of pubertal events and a different pattern of ovarian and adrenal hormones.Methods: A total of 583 girls from the longitudinal cohort (Growth and Obesity Cohort Study, born 2002) wer...

Pseudohypoparathyroidism Type IB Associated to Assisted Reproductive Technologies: Case Report

Fernandez Monica , Riquelme Joel , Castiglioni Claudia , Jueppner Harald W , Mericq Veronica

Background: Pseudohypoparathyroidism type Ib (PHP-Ib) is due to a maternal loss of GNAS exon A/B methylation and leads to decreased expression of the stimulatory G protein (Gsα) in specific tissues. Evidence suggests an increased incidence of imprinting disorders in children conceived by Assisted Reproductive Technologies (ART). Nevertheless, no associations between ART and PHP – Ib have been found to date.Clinical case: 7.4-years-old male with...

Premature Adrenarche and Metabolic Risk: Differences by Gender

Pereira Ana , Merino Paulina M. , Iniguez German , Corvalan Camila , Mericq Veronica

Background: Premature adrenarche (PA) has been considered a benign condition. Recently, associations with an increased metabolic risk have arisen. This risk may depend on ethnic background and infancy weight gain, which could be different by gender.Objective and hypotheses: To determine whether PA in children at pubertal onset (TII) determines a higher metabolic profile.Methods: 1190 children (49.9% female) from the longitudinal co...
